To all 'whom @'15 may cof/wem:

Be it hnownthat We, GEORGE lV. PRINCE and ARCHIBALD DOUGLAS, citizens of the iUnited States, and residents, respectively,

5.0i Clemenceau, in the county of Yavapai and State of Arizona, and of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Smelting Furnaces and the Method of Smelting Orcs Thea-ein, of which the following is a specification.'

The object of this invention lis to provide -novel means for and method oi feeding ores into a reverberatory furnace whereby a more I5 rapidf andl effectivev smelting ot' .the ores as well as great economy in fuel is obtained by 'depositing .the oresv on--the Hoor of the furnace, to form a plurality of continuous lon-l fritudinal mounds with their apices space rom each other und from the unettled sid Walls of the furnace, the outer sides of the mounds sloping to the said side walls of the furnace to form valleys for the flow of the molten material along the side Walls and between the mounds. l

A further object is to provide lmeans for feeding the ores into the furnace" substantially continuously so that the/continuous lonvitudinal mounds l will bei'A maintained during the smelting operationen-: i thereby the most effective aud-:economical smelting -of the ores may be obtained.

In the.. accompanying drawings;

Fig. l represents a reverberatory furnace in horizontal section with the improvements incorporated therein.

Fig. 2 represents a longitudinal vertical section throu h the furnace, taken in the plane ofthe luie Ilo-IL of Fig.

Fig. 3 represents a transverse vertical sec'- tion through the furnace taken in the plane on the line IlI--III of ig. 2.

The furnace door is represented b 1, the arched roof by 2 and the uufettled si' e Walls by 3, 4.. This furnace may be rovided at rows of cosaiy spaced passages 7, the rows..

,being about @smellyv distant from 4maintained at the its x'oor end with the usual nozz es 5 for inthe side walls, through ores are Afed in from eachother and from which passages the 'gated hoppers 8, communicating with a suit of the furnace, thereby producing valleys between the adjacent sloping sides of thc mounds and also between the outer sides of the mounds and the side Walls of the furnace, along which valleys the vmolten material Hows to the fiue end of the furnace.

It is intended that this feeding of the ores shall be substantially continuous so that the continuous longitudinal mounds will be proper height to utilize the efi'ect of the economically and at the same time to present a very extended ore surface to the aotion of said heating medium. This substantially continuously feeding in of the ores, as distinguished from periodic feeding in,` permits the orcs to be submitted to the X action of the heating medium at .a time whenthe ores most readily absorb the heat of the heating medium.

If found necessary, a greater or lesser porr tion of each of the side walls /may be made of non-corrosive material such, for instance, as magnesite or chrome bricks 10, where the molten material comes into contact with the said side walls.'

What We claim is l. The method of smelting ores in rever-y beratory furnaces which consists in substantially continuously feeding the ores into the furnace chamber in such 9L manner that a pluralityof continuous longitudinal mounds are formed and maintained with the apices spaced from each other and from the side walls of the furnace chamber, and subjecting the mounds to the action 'of a heating me- 2. The method of smelting ores in reverberatory furnaces which consists in substantially continuously feeding the ores into the -furnace chamber in sucha manner that two' continuous longitudinalmounds are formed and from each other and. from the-side We s of the fur ce chamber, and subject l s the mounds' to the action of a heating ,zum l heating medium most maintained with their. apices. s aoed. i955 3.
